Whether you have fiber supplying Internet access to your home or not, you use optical systems to send and receive information every single day. This stunning video takes a look at the scientists and engineers that have enabled light to be used for human communication.

Ricocheting between Oxford, Stuutgart, Paris and New Jersey, with interviews of “Nobel Laureates, semi-retired German eccentrics and impassioned geeks”, the video explores the folks from Bell Labs who push the boundaries of how much infromation can be encoded using just light. It’s pretty, fascinating and inspirational.
